The total amount of fiat money in the world is over 80 trillion- This is a conservative estimate and it much higher. The crypto market will grow very rapidly over the next 2 years. At the end of 2018 it should be minimum 1 trillion total. At the end of 2019 it will be over 5 trillion.
My mathematical formulas tells me bitcoin will be somewhere between 46,653-57,259 at the end of this year.
I am not certain about the amount of fiat money in circulation around the world but i do like to know how you calculated the price at the end of this year, the said price could be attained without a doubt in the long run , but cannot predict exactly it could happen this year. I am would like to see the total asset valuation to cross over a trillion dollar in a few years .
